Thanks for using Petco Pet Education Center, formerly Petcoach! These types of behavior can improve though this does require in person training with the help of a qualified dog trainer. I would encourage you to contact a dog trainer that can work with you and Bruno in person to really take care of this behavior. The sooner these behaviors are dealt with, the more likely it is that you can improve and resolve them. Good luck and have a great day!
